Season pork chops with salt and pepper.
Heat 1 tbsp (15 mL) oil in a heavy or cast iron skillet set over medium-high heat.
Add pork chops and sear for 4 to 5 minutes per side or until well-browned. Transfer to a plate.
Reduce heat to medium. Add remaining oil, onion, garlic and thyme to skillet. Cook, stirring occasionally, for 15 minutes or until onions are well-browned.
Stir in wine, broth and Worcestershire sauce. Bring to a simmer.
Nestle pork chops into skillet. Simmer, partially covered, for 15 minutes or until just a hint of pink remains (or pork is cooked to preferred completion).
Remove pork chops to a platter. Spoon pan sauce over top and sprinkle with parsley (if using).
